Intel Core 7 251TE vs Intel Core 7 350 Comparison

The Verdict

The Intel Core 7 251TE is the overwhelming performance leader in this comparison, winning 15 of the 17 recorded head-to-head benchmarks. Its average benchmark score of 41650 places it in the 88th percentile of all CPUs, while the Intel Core 7 350 averages 17779 and sits in the 71st percentile. The 251TE delivers more than double the average score, 134.2% higher than the 350, making it the clear choice for any workload where compute throughput is the priority.

The Intel Core 7 350 does win two benchmarks, both in single-threaded PassMark testing. Its PassMark single-thread score of 4100 is 13% higher than the 251TE's 3568. This makes the 350 the better option for lightly threaded, single-core-dependent tasks where that specific metric matters most. However, this advantage is narrow and isolated, and it does not translate to wins in Cinebench single-core tests, where the 251TE leads by 24% in R15, 99.5% in R20, and 76.1% in R23.

For system builders and mobile device planners, the choice depends on the workload profile. The 251TE is a desktop part with 24 cores, 32 threads, and a 45 W TDP, suited for heavy multi-threaded work. The 350 is a mobile part with 6 cores, 6 threads, and a 15 W TDP, suited for power-constrained environments where single-thread PassMark performance is valued. The recorded data shows no scenario where the 350 competes with the 251TE in multi-threaded throughput, with the 251TE leading by margins from 30.8% to 272.7% across all multi-threaded tests.

Architecture Differences

The two processors come from different Intel families and use different manufacturing processes. The Intel Core 7 251TE is built on the Bartlett Lake architecture, uses a 10 nm process node, and is a desktop part on Intel Socket 1700. The Intel Core 7 350 uses the Wildcat Lake architecture, employs a 3 nm process node, and is a mobile part on Intel BGA 1516.

The core configurations diverge sharply. The 251TE has 24 cores and 32 threads, indicating a hybrid layout with additional efficiency cores. The 350 has 6 cores and 6 threads, with no hyper-threading support evident from the equal core and thread counts. This structural difference drives the massive multi-threaded performance gap.

Cache hierarchies also differ significantly. The 251TE has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 36 MB of shared L3 cache. The 350 has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 6 MB of shared L3. While the per-core L1 and L2 caches are larger on the 350, the total L3 cache is 6 times smaller, limiting the data that can be shared across the processor.

Memory support and PCIe capabilities differ as well. The 251TE supports DDR4 and DDR5 memory over a dual-channel bus with 89.6 GB/s bandwidth and ECC memory support. The 350 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s bandwidth and no ECC support. The 251TE offers PCIe Gen 5 with 16 CPU lanes, while the 350 offers PCIe Gen 4 with 6 CPU lanes.

Integrated graphics are another distinction. The 251TE uses UHD Graphics 770, while the 350 uses Intel Xe3 Graphics with 2 Xe cores. The production status for both is Active, though the release dates differ: the 251TE released on 2025-01-12, and the 350 released on 2026-04-15.

Specification Differences

The recorded specifications show a clear split between the two parts. Core count differs: 24 cores for the 251TE versus 6 cores for the 350. Thread count differs: 32 threads versus 6. Base clocks are close, 1.40 GHz versus 1.50 GHz, but boost clocks favor the 251TE, 5.40 GHz versus 4.80 GHz.

TDP is a major differentiator. The 251TE has a 45 W TDP, while the 350 has a 15 W TDP. This indicates the 350 is designed for low-power mobile operation, while the 251TE targets desktop performance.

Socket types are incompatible: Intel Socket 1700 for the 251TE and Intel BGA 1516 for the 350. The process node differs, 10 nm versus 3 nm, which explains the 350's smaller die size (no die size recorded) and lower power draw despite the newer node.

Memory support differs in type and channel count. The 251TE supports DDR4 and DDR5 dual-channel, while the 350 supports DDR5 and LPDDR5X single-channel. Memory bandwidth reflects this: 89.6 GB/s versus 59.7 GB/s. ECC support is present only on the 251TE.

PCIe generation and lane counts differ: Gen 5 with 16 lanes for the 251TE versus Gen 4 with 6 lanes for the 350. Integrated graphics differ: UHD Graphics 770 versus Intel Xe3 Graphics (2 Xe). The launch MSRP is $384 for the 251TE and $469 for the 350. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head data shows a dominant performance profile for the Intel Core 7 251TE across nearly every test. In Cinebench R23 multi-core, the 251TE scores 25518 against 8030 for the 350, a 217.8% advantage. This is the largest Cinebench margin recorded. PassMark integer math shows an even larger gap: 125739 versus 33734, a 272.7% difference.

The 251TE also leads decisively in floating-point math, scoring 85607 against 42809, a 100% advantage. Data compression favors the 251TE by 133.6%, with scores of 334399 versus 143123. Data encryption shows a 102.8% lead, 22176 versus 10933. Random string sorting shows a 130% lead, 39643 versus 17238.

Multi-threaded PassMark testing confirms the trend. The 251TE scores 30022 versus 15170, a 97.9% lead. Physics simulation scores 1938 versus 1173, a 65.2% lead. Extended instructions score 16974 versus 12045, a 40.9% lead. Find prime numbers scores 140 versus 107, a 30.8% lead.

Cinebench R15 and R20 results follow the same pattern. Multi-core R15 shows a 110.8% lead, 2572 versus 1220. Single-core R15 shows a 24% lead, 362 versus 292. Multi-core R20 shows a 99.5% lead, 10717 versus 5373. Single-core R20 shows a 99.5% lead, 1512 versus 758. Cinebench R23 single-core shows a 76.1% lead, 3602 versus 2046.

The only wins for the Intel Core 7 350 are in PassMark single-thread tests. Both the single-thread and singlethread entries record identical scores: 4100 for the 350 versus 3568 for the 251TE, a 13% advantage. This is the sole area where the 350 outperforms the 251TE, and it does not appear in any Cinebench single-core test.

Where Each One Wins

The Intel Core 7 251TE wins in all multi-threaded workloads, all Cinebench tests, and most PassMark tests. Its 24-core, 32-thread configuration delivers massive throughput advantages in integer math, floating-point math, data compression, encryption, physics simulation, and random string sorting. The data shows it is the stronger processor for rendering, compilation, scientific computing, and any workload that scales with core count.

The 251TE also wins in Cinebench single-core tests, despite having a lower PassMark single-thread score. Its boost clock of 5.40 GHz and larger L3 cache of 36 MB likely contribute to these wins. The R23 single-core score of 3602 versus 2046, a 76.1% lead, is substantial and indicates the 251TE is faster even in some single-threaded scenarios.

The Intel Core 7 350 wins only in PassMark single-thread tests, with a 13% advantage. This suggests the 350 has a higher per-core performance in that specific benchmark, likely due to its 3 nm process node and larger per-core L1 and L2 caches. The 192 KB L1 and 2.5 MB L2 per core are larger than the 251TE's 80 KB and 1.25 MB, which may improve single-thread latency-sensitive workloads.

The 350's lower TDP of 15 W versus 45 W makes it the appropriate choice for fanless or battery-powered mobile designs where the single-thread PassMark score is the primary performance metric. The 251TE, with its 45 W TDP and desktop socket, is the appropriate choice for desktop systems where the 15 recorded benchmark wins and the 88th percentile ranking provide superior overall performance.
